Jason Escobar joins the Lunar Management Company and lifts for the moon. There, he meets Charlemagne Beckman and begins to understand the workers on the moon, called "Lunatics," and their desire for freedom from the company he works for. Poor working conditions and low wages propel the Lunatics to demand action. With his new lover, Martin Kauri, Jason is thrown into the rebellion and must decide where his duty lies. The coming confrontation will bring the Lunatics together and force Jason to choose between freedom and his love for Martin or his obligation to the LMC.
